Interacoustics MT10 Middle Ear Analyser Tympanometer
Excl. Tax: £2,995.00 Incl. Tax: £3,594.00


The Interacoustics MT10 audiometer and printer is built to accommodate modern health-care settings where fast and reliable testing is paramount.

The MT10 audiometer is well suited for diagnostic use as tympanograms and optional reflex responses are all recorded in great detail. With the MT10 you can detect
otitis media, a perforated eardrum, cholesteotomas and certain neurological disorders.  You can also check tympanostomy tubes and follow up on post medical treatments.

Four different reflex tests may be performed per ear using either fixed or automatic intensity selection.  The test is carried out at the correct pressure level and the actual reflex characteristics are displayed on the screen for the operator to view and interpret.

• 4 frequencies (500, 1000, 2000, 4000 Hz)
• Single or multiple dB level threshold search
• Auto detection of threshold

The Interacoustics MT10 tympanometer can hold test results of up to 30 patients in its memory. This makes it possible to screen a large group of patients and print out the data at a later time.
